Android常用ProgressDialog设置

public static ProgressDialog initDialog(Context context) {

		ProgressDialog progressDialog = new ProgressDialog(context);

		progressDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);

		progressDialog.setCanceledOnTouchOutside(false);

		progressDialog.setMessage("loading...");

		//使其按下Back键无用

		progressDialog.setCancelable(false);

		//使其点击对话框以外的地方不起作用

		progressDialog.setCanceledOnTouchOutside(false);

		//使其按下Search键无用

		progressDialog.setOnKeyListener(new OnKeyListener() {

			@Override

			public boolean onKey(DialogInterface dialog, int keyCode, KeyEvent event) {

				if (keyCode==KeyEvent.KEYCODE_SEARCH) {

					return true;

				}

				return false;

			}

		});

		return progressDialog;
